Method and apparatus for dispensing viscous material

Abstract

A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The compression head cap further includes a plurality of members which are selectively and movably disposed within the contained environment and which selectively remove an amount of the material from the environment, effective to prevent the material from being undesirably dispensed by the head cap.

What is claimed is:  
     
       1. A print assembly for use in combination with viscous material, said print assembly comprising: 
       a print head having at least one chamber which selectively receives said viscous material and which selectively allows said received viscous material to be selectively dispensed from said print head; and  
       at least one member which is selectively and movably disposed within said at least one chamber and which selectively removes a certain portion of said received viscous material from said at least one chamber, effective to selectively prevent said removed viscous material from being dispensed by said print head;  
       wherein said chamber is formed by at least two walls, said print assembly further including a blade which is coupled to one of said two walls and which forms an angle with said one of said two walls of about from about 20 to about 80 degrees.
